About the Aspect Ratio Calculator
The Aspect Ratio Calculator is an essential utility for video editors, designers, and social media managers. It helps you accurately calculate the correct dimensions to maintain a video's aspect ratio when resizing. Whether you're converting a widescreen video for a vertical platform or cropping content to fit a specific frame, this tool ensures your visuals never look stretched or distorted.

Use Cases
Social Media Managers

Video Editors

Graphic Designers
Determine the pixel dimensions needed for a graphic that will be used in a video project with a specific aspect ratio.
Web Developers
Calculate the height of a video container when you only know the width and need to maintain a 16:9 aspect ratio to prevent layout shift.
Pro Tips
Know Your Platforms
Different platforms favor different aspect ratios. 16:9 is standard for YouTube, but 9:16 is essential for mobile-first platforms like TikTok and Instagram Reels.
Beware of "Safe Zones"
When creating vertical video (9:16), remember that the platform's UI (like captions and buttons) will cover the bottom and top parts of the screen. Keep your most important visual information in the center.
Aspect Ratio vs. Resolution
Aspect ratio is the shape of the video (e.g., 16:9), while resolution is the number of pixels it contains (e.g., 1920x1080). You can have many resolutions with the same aspect ratio.
Use Presets for Speed
If you frequently work with standard formats, use the preset buttons to quickly load common dimensions like 1080p for 16:9 or 1080x1920 for vertical video.
